TO ALL WHOMv IT MAY GONGERN:

Beit known that I,JO1V1N B. WILSON, of New York, oi' thcfcounty of. New York, in the State of New York, have invented4 a new Method of Cutting Veneers); and I do hereby declare that the following is a full and exact description thereof, reference being had 'to the accompanying drawings, making part of this application.

My invention relates to a novel method of Cutting veneers, and has for its object to produce, from a plain log, veneers with considerable variety of grain, and from'logs possessing igure, a greater variety of iigure than has been obtained by the method of cutting heretofore practised. Previous to my invention it has been customary to slab olf the veneers or thin boards'froru a log with a plain or straight knife in such manner that cach cut would take olf a stratum of wood equal in length and widtlrto the (cut)surface' of the log, and in shape almost a perfect plane, having only the curvature of the'arc in which the log was vibrated in the machine. I have discovered that by making the knife or cutting tool of a corrugated or crimped shape throughout its length, and cutting with such shaped knife aveneer which shallbe correspondingly corrugated, (crosswise oft-he vcneer,) the -vcnecr will possess a much greater variety of grain or figure when pressed out ilat or smooth, and find that by so cutting the wood I can produce from a perfectly `plain log adigured veneer, and from a log possessing figure a more highly or beautifully figured veneer. And my invention consists in producing veneers by cutting them from the login a corrugated or crimped shape, substantially as hereinafter more fully described.

To enable those skilled in the art to fully comprehend my invention, YI will proceed to describe it more in detail, referring to letters in the accompanying drawing, in which I have illustrated a Veneer-cutting machine adapted to carry out my invention. In the accompanying drawings- Figure l is a top view of a veneer-cutting machine, having its cutting device so constructed as to vproduce veneers upon my new method'of cutting them.

Figure 2 is a vertical section at line :c x, fig. 1; and l Figure 3 is an edge view of aveneer as it appears when it comes from the machine.

The general construction and operation of themachine showrnwith the exception of the cutting device, is about .the same as that of machines already in use, and with which those skilled in the art are familiar.- I need therefore only allude to it in a general way. y 1

A is the frame of the machine arranged and supported upon a suitable ilocr or foundation, B. On the frame A is mounted in suitable bearings or boxes c, a rock-shaft, D, to which is attached the vibratoryframe E, tothe face of which the log Fis secured by bolts in the usual manner. Opposite to the face or log surface of the vibratoryframe E is arranged on the frame of the machine the knife-'stock or stand G, in which is located the cutting or shaving device. The frame E is vibiratedor rocked on its shaft D in the usual manner by means of pitmans, H H, connected to the cranks of any suitable driving machinery, andthe boxes, C, are constructed and arranged so as to slide on ways, I I, formed on the frame A, in order that the log F may be fed toward the cutting or shaving mechanism. The feed is cii'ectcd by means offeed-screws, KK, working through the stands of boxes .C C, and arranged in stands m, as clearly seen. The screw-shafts are provided on their outer ends with wheels, N, connected by a belt, O, and may be operated by hand or automatically from the driving meehani ism, if deemed expedient. S is the corrugated or crimped cutting or shaving tool or knife, which is arranged in and fastened to the tool-stock G, (as clearly shown,) in such manneras to shave or cut olf a-thin stratum of the log F, or a veneer each time the frame E is fed toward the cutter and caused to descend, as illustrated at iig. 2, where t represents the veneer (in section) being cut by the knife S. As the veneers are cut or slabbed olf, they discharge or pass out of the machine, as illustrated (inthe direction of the arrow, iig. 2.) The shape of the veneer cut is clearly illustrated in the edge view of Vthe same at fig. 3, from which it will be' seen to be l of a wave-likey or crimped shape.l After the veneer is cut of this shape it may be smoothed or pressed flat, and

when ready for use will present a plane slrape similar to the ordinarily cut veneer. it will be seen by thus cutting or shaving off the wood in corrugated orcrimped strata, in lieu of straight with the grain, the dilfercnt grains of the wood will bc penetrated in cach cut and shown in the surfaceof the veneer, and thus the great desideratum of producing a figured veneer from a' plain log, or increasing the figure of a log possessing ligure hereinbefore alluded to, 'is accomplished. Of course the form and size of the corrugations in the knife may be infinitely varied without departing from the spirit of my invention, and it may beeven. possible to cut the veneer in the manner or shape described without a. corrugated knife, by shoving it off longitudinally. I therefore wish it to be understood that I do not propose to limit my claim of invention to the peculiar form of knife sl1own,"or to any details of machinery, but having explained the objects and advantages of my invention, und the mode in which I have successfully carried it out or practised it, A

What I elaim as new, and desire to-secure by Letters Patent, is-

Cutting a. crimped or corrugated veneer, substantially as Vdeseribed, for the purpose set forth.

In testimony whereof I have hereunto set my hand und seal this 24th day of January, 1867.
